摘要: 根据单种煤的镜质体反射率实测分布图,按照直方图的合成原理,统计出各反射率区间的频率,制定 出人工合成配合煤镜质体反射率分布图的方法。此方法可以方便地计算出多种煤不同配比时的镜质体反射率平 均值(Rr)和标准差(S),并绘制出配合煤的镜质体反射率分布图,减少了复杂的化验过程和高昂的化验费用, 在选煤和配煤方面具有很好的推广利用价值。

Abstract: This paper shows the frequency of each reflectance interval and the method of generating a vitrinite reflectivity distribution chart of mixed coal based on histogram generation principles and the vitrinite reflectivity distribution of single coal. It calculates average vitrinite reflectance(Rr) and standard deviations(S)of mixed coal under different ratios and generates a vitrinite reflectivity distribution chart so to save time and cost of laboratory work,which could be widely applied in coal blending and coking-coal mixing process.

Key words: Vitrinite, Reflectance, Distribution chart, Half-order, Frequency, Coal blending
